With burgeoning interest in the low-altitude economy, applications of long-endurance unmanned aerial vehicles (LE-UAVs) have increased in remote logistics distribution. Given LE-UAVs’ advantages of wide coverage, strong versatility and low cost, in addition to logistics distribution, they are widely used in military reconnaissance, communication relay, disaster monitoring and other activities. With limited autonomous intelligence, LE-UAVs require regular periodic and non-periodic control from ground control resources (GCRs) during flights and mission execution. However, the lack of GCRs significantly restricts the applications of LE-UAVs in parallel.

We consider the constraints of GCRs, investigating an integrated optimization problem of multi-LE-UAV mission planning and GCR allocation (Multi-U&G IOP). The problem integrates GCR allocation into traditional multi-UAV cooperative mission planning. The coupling decision of mission planning and GCR allocation enlarges the decision space and adds complexities to the problem’s structure. Through characterizing the problem, this study establishes a mixed integer linear programming (MILP) model for the integrated optimization problem. To solve the problem, we develop a three-stage iterative optimization algorithm combining a hybrid genetic algorithm with local search-variable neighborhood decent, heuristic conflict elimination and post-optimization of GCR allocation.

Numerical experimental results show that our developed algorithm can solve the problem efficiently and exceeds the solution performance of the solver CPLEX. For small-scale instances, our algorithm can obtain optimal solutions in less time than CPLEX. For large-scale instances, our algorithm produces better results in one hour than CPLEX does. Implementing our approach allows efficient coordination of multiple UAVs, enabling faster mission completion with a minimal number of GCRs.

Drawing on the interplay between LE-UAVs and GCRs and considering the practical applications of LE-UAVs, we propose the Multi-U&G IOP problem. We formulate this problem as a MILP model aiming to minimize the maximum task completion time (makespan). Furthermore, we present a relaxation model for this problem. To efficiently address the MILP model, we develop a three-stage iterative optimization algorithm. Subsequently, we verify the efficacy of our algorithm through extensive experimentation across various scenarios.

We investigate the relation between corporate culture and the likelihood of discontinuing business operations.

We rely on regression analysis in our study.

We find a significant negative relation, suggesting that firms with strong corporate culture are less likely to discontinue business operations. To enhance the incremental contributions of our study, we delve into the moderating role of corporate culture on the aforementioned relation and identify several factors that, when coupled with corporate culture, could indirectly impact the decision-making process regarding discontinuing operations. We also find that the negative relation between corporate culture and discontinued operations is mainly driven by firms with lower earnings performance, and this relation becomes stronger for high-tech firms. Lastly, we find that stronger culture is associated with a larger magnitude of discontinued operations for firms reporting discontinued operations, and this positive association is largely driven by firms reporting income-decreasing discontinued operations.

Our analysis adds to two independent streams of research: corporate culture in management literature and discontinued operations in accounting literature. Prior research, in particular, focuses on examining if and how managers exploit discontinued operations to manipulate earnings. By showing a significant negative impact of corporate culture on the likelihood of discontinuing business operations, our research undoubtedly adds to the body of understanding regarding the factors that lead managers to discontinue certain operations.

The purpose of this study is to examine the underlying mechanisms of exploitative innovation and exploratory innovation between social media usage and organizational agility, and elucidate the moderating role of learning goal orientation (LGO) in the above relationships, based on adaptive structuration theory (AST).

Based on a multiple-respondent matched survey of 334 Chinese e-commerce firms, authors employed structural equation modeling to examine the correlations among social media usage, exploitative innovation, exploratory innovation and organizational agility. Hierarchical regression analysis was used to examine the moderating role of LGO.

This study's empirical findings demonstrate that exploitative innovation and exploratory innovation mediate the relationship between social media usage and organizational agility in different ways. Further, LGO positively moderates the relationship between social media usage for customer acquisition and exploratory innovation, as well as the relationship between social media usage for customer relationship and exploitative innovation.

Firms are advised to leverage different types of social media usage to facilitate exploitative innovation and exploratory innovation and promote organizational agility. In addition, LGO within a firm should be established to enhance the effects of social media usage on exploitative innovation and exploratory innovation.

This study adds to the literature on social media usage by proposing and examining exploitative innovation and exploratory innovation as explanatory mechanisms to facilitate organizational agility. This study further identifies LGO as a boundary condition of social media usage's effect on exploitative innovation and exploratory innovation. By contextualizing social media as advanced information technology, this study contributes to the contextualization of AST in the social media context.

In recent years, organizations have progressively adopted electronic performance monitoring (EPM) to obtain accurate employee performance data and improve management efficiency in response to the growing complexity of the work environment. However, existing research has primarily focused on examining the effect of EPM on employee behaviors within established job designs, neglecting the consequential role of EPM in shaping employees’ bottom-up job redesign (i.e. job crafting). This study aims to explore whether and how EPM affects employee job crafting.

To test proposed hypotheses, we conducted two time-lagged surveys across different cultural contexts and a scenario experiment on an online platform in China.

The results revealed the negative indirect relationship between EPM and employee job crafting via role breadth self-efficacy. This indirect relationship was moderated by constructive supervisor feedback and job complexity, with the above relationships being weak (versus strong) when constructive supervisor feedback was high (versus low) or job complexity was low (versus high).

The results have crucial implications for organizational practices, suggesting that managers should provide constructive feedback to break the trade-off between EPM and job crafting. Additionally, managers may need to give employees with high job complexity more autonomy rather than intense monitoring.

This study is the first to clarify the effect of EPM on employee job crafting. As job crafting captures the important value of employees in organizational job design, our effort helps to enrich the understanding of EPM effectiveness.

Building on stimulus organism response theory, the current study examines the influence of channel integration quality dimensions (channel service configuration and integrated interactions) on the omnichannel retail store's shoppers' satisfaction, trust and commitment, subsequently leading to customer citizenship behavior (CCB). It examines the relationships proposed against boundary conditions, the number of channels used during the purchase and gender.

The research is descriptive, quantitative and cross-sectional investigation. It was conducted using data from 451 Indian omnichannel shoppers using a validated self-administered questionnaire. The proposed conceptual model was tested using PLS-SEM and PLS-MGA.

The results indicate that channel service configuration positively impact the dimensions of relationship quality of the omnichannel shoppers. However, integrated interactions influence trust and commitment directly but affect satisfaction indirectly through trust. Subsequently, relationship quality significantly explains CCB. The model results show r2 = 0.402 for CCB; that is, 40.2% of CCB is explained by channel integration and relationship quality. The moderating effect of the number of purchase channels used and gender on all proposed relationships were tested. PLS-MGA results revealed channel service configuration led to shopper commitment, subsequently impacting CCB. The effect was more among shoppers who used more than 2 channels. The impact of channel service configuration on commitment was seen more among female shoppers. Male and female shoppers exhibited satisfaction-driven and trust-driven citizenship behavior, respectively.

The study is carried out in the Indian population, where omnichannel retailing is still in the nascent stage.

This is the first study to demonstrate channel integration quality may influence customer citizenship behavior through relationship quality dimensions, tested against boundary conditions, the number of channels used during the purchase and gender. The findings from this research would help retail store managers design their omnichannel operations to encourage firm-beneficial value co-creation behaviors among omnichannel shoppers.

This study aims to analyze the push and pull factors and its relationship with the theory of planned behavior about non-vegetarians’ intentions to buy plant-based meat products. Previous studies seldom explored the intention of non-vegetarians’ intention to buy plant-based meat products.

An online survey was conducted among 447 non-vegetarians to investigate these relationships. Partial least squares-structural equation modeling (PLS-SEM) was employed to scrutinize the data.

Among the push factors product safety and flavor positively influence consumers’ attitude, whereas environmental protection and flavor positively influence subjective norms. Animal welfare, environmental protection and flavor positively influence perceived behavioral control. Among the pull factors, curiosity, product nutrition and price positively influence consumer attitudes toward plant-based meat products. Curiosity and price also positively influence subjective norms, but only product nutrition positively influences perceived behavioral control. On the other hand, the results also confirm that non-vegetarian customers' intentions to buy plant-based meat products is primarily influenced by attitude and perceived behavioral control, whereas subjective norms do not influence the intention to buy plant-based meat products. This study also reveals that there exists a moderating influence from perceived behavioral control between attitude and intention to buy plant-based meat products, whereas the moderating effect of perceived behavioral control on subjective norms and intention is insignificant.

The findings of this study offer practical recommendations for persuasive marketing strategies associated with plant-based meat substitutes.

The literature on knowledge management in sustainable supply chain (KMSSC) has witnessed significant growth in the past two decades. However, a scientometric review that consolidates the primary trends and clusters within this topic has been notably absent. This paper aims to scrutinize recent advancements and identify the intellectual underpinnings of KMSSC research conducted between 2002 and 2022.

The present review employs a scientometric analysis approach via visualization maps of prolific contributions, co-citation, co-occurrence and thematic networks to examine a total of 114 articles and conference papers on KMSSC.

Emerging research frontiers and hotspots are revealed and a state-of-the-art framework of KMSSC research structure is developed.

The review provides significant implications that guide KMSSC research and better inform sustainability decisions in the supply chain context.

To the best of the authors' knowledge, this is the first review to thoroughly synthesize the intersected domain of KMSSC using scientometric analysis.

The purpose of this study is to explore how to select a suitable supply chain collaboration paradigm (SCCP) based on the intelligent manufacturing model (IMM) of enterprises.

Given the fit between internal collaboration and external collaboration, we propose a model to select a suitable SCCP based on two-sided matching between SCCPs and IMMs. In this decision problem, we invited five university scholars and seven related consultants to evaluate SCCPs and IMMs based on the regret theory, which is used to obtain the perceived utility and matching results. The evaluation values are comfortably expressed through probabilistic linguistic term sets (PLTSs). Also, we set the lowest acceptance threshold to improve the accuracy of matching results.

The findings indicate that the characteristics of IMMs can significantly influence the selection of SCCPs, and an SCCP is not suitable for all IMMs. Interestingly, the study findings suggest that the selection of SCCP is diverse and multi-optional under the constraints of IMMs.

Existing studies have explored supply chain collaboration (SCC) in Industry 4.0 to improve supply chain performance, but less attention has been paid to the impact of the match between SCCPs and IMMs on supply chain performance. And even fewer studies have addressed how to select a suitable SCCP in different IMMs. This study provides a unique contribution to the practice of SCC and expands the understanding of supply chain management in Industry 4.0.

This research investigates the role of customer forgiveness as the result of online service recovery transparency in predicting customer engagement. It also examines the moderating roles of timeliness and personalization in this proposed model.

An online survey study using retrospective experience sampling and a scenario-based experimental study were conducted to test the proposed hypotheses.

Customer forgiveness positively influences customer engagement and plays a mediating role in the relationship between service recovery transparency and customer engagement. Additionally, timeliness and personalization moderate the positive influence of service recovery transparency on customer forgiveness. The positive influence of service recovery transparency on customer forgiveness is more apparent when levels of timeliness and personalization decrease.

To retain focal customers' engagement after a service failure, firms must obtain their forgiveness. One of the firm's online complaint handling strategies to increase the forgiveness level of focal customers is to provide a high level of service recovery transparency (i.e. responding to their complaints in a public channel), especially when the firm is unable to respond to online complaints quickly or provide highly personalized responses.

This research provides new insights into the underlying mechanism of customer engagement by applying the concept of customer forgiveness. It also contributes to the social influence theory by applying the essence of the theory to explain how other customers' virtual presence during the online complaint handling influences the forgiveness of focal customers in order to gain their engagement. Additionally, it provides insight into the conditions under which the role of service recovery transparency can be very effective in dealing with online complaints.
